The video discusses two advanced cloning techniques: embryo transplants and adult cell cloning. Embryo transplants involve splitting a developing embryo into multiple embryos, which are then implanted into host mothers to produce genetically identical offspring. This method is used to produce many offspring from valuable animals. Adult cell cloning involves transferring the nucleus of an adult cell into an unfertilized egg, stimulating it to develop into an embryo, and implanting it into a host mother. This technique was used to clone Dolly the sheep and is still under research.

What was the significance of Dolly the sheep in the context of cloning?

What are the potential applications and current status of adult cell cloning?
